2003 Corolla Tranny and Spark Plug change?

[Boogalou]

Anyone know when the transmission oil and plugs should be changed on a 2003 Corolla. We lost the manual and I can't find any info online. The guy at Auto Zone said not to even worry about it until 75k miles or so but that seems like a bit much.

Any help would be greatly appreciated!

Thanks,

Boog

I suppose its a manual transmission, because in those you change the oils like every 40,000km or so (or if the tranny starts to misshift, etc)

It's an automatic and believe it or not my sister findally found the manual and it says under normal driving conditions the fluid will _never_ need to be changed??? And on the transmission dip stick it says it does not need to be changed???!!! Are they using new super ATF now? Geesh.

And the spark plugs supposedly last for a minimum of 60k. The manual doesn't require that they be changed until 120k??? This sounds crazy.

Does this sound right to you guys?

Btw, it has 30k miles on it. I'm thinking of waiting until 60k then changing both?

You have irridium plugs they last much longer than platinum.

If your worried just change them out anyway at 60,000 miles.

I wouldn't do the ATF unless the fluid on the stick looks crappy or you are having problems.

I have the same thing with my 2004 corolla it says to possibly replace the transmission fluid at i think 150,000 and the spark plugs are like 100k its crazy but im afraid if atf is in there that long it will become sludgy and screw up the transmission

You can look at the fluid whenever you want by pulling the dipstick. If it becomes overly clouded you can change it.
Your tranny will not get instantly screwed up, if your fluid is so cooked that it starts to affect the tranny, you will feel the difference long before any permenant dammage is done.

if its automatic tranny........@80,000km or 50,000 miles and the spark plugs@192,000 km or around 118,000miles

How on earth can transmission fluid last 150k????

Wouldn't it break down by then?

I'm changing mine at 60k I think.

I had toyota flush the tranny fluid in my automatic at a little over 100K the plugs today at 107300 miles.

Use this link and look up the service requirements of your Corolla, I got it through toyota.com and it's found under the owners tab.

You guys better check your scheduled maintenance books ...I have an 03 and it says in my automatic the ATF fluid gets changed every 30-60-90-120 miles and so on! Meaning every 30 thousand... How could anyone here suggest waiting till 150K for a ATF change or suggesting changing fluid when it looks bad, cloudy or crappy by then it might already have done damage ...Hope your cars are still running don't know how with that thinking

yes like radd said, the major service intervals. ANd i believe they check ur plugs then too.

PS. At my dealership i got this agreement every major service interval I get a loaner car. Plus a bunch of free stuff and rebates.

It doesn't say to change the auto tranny fluid every 30K miles.

[Raddman]

It doesn't say to change the auto tranny fluid every 30K miles.

Its in it your scheduled maintenance book which I would think it means it a service that needs to be done at that mileage, Where are you getting your info from that says different or is it just your opinion

Post a pic of the page in the toyota manual where it says to change every 30K miles and I'll send you $20.

It may say inspect, but inspect does not mean change.
